Quote: Yes and no. Your description is a little unclear. The shoulder width across the top part of the shoulders is the point to point measurement. If you want the jacket to be wider at the top of the shoulder you can only let out the center back seam from the collar to the waist. There is no outlet at the shoulder pint where the sleeves are attached unless it is custom made and the tailor left outlets. I am not sure if you need 3/8" on each side of the center back seam or 3/8" total across the whole back. If you let out either amount on the center seam it creates a couple problems. The collar becomes too small for the neck yoke. The center back seam becomes very curved and will lay differently across your blades. May be good, may be bad. You will see a very small, if any, difference from the front view. If the jacket is tight across the back, first let it out at the under arm of the side body and see how much better the jacket feels. If you need more, try letting out the center back seam. Hi Despos. I will see the tailor today and I want to talk with him about this issue you told me. Here are two new pics, my mom have a terrible pulse, so they came out a bit unclear, but I think I can ilustrate my point. This one is more useful, I think. I have one suit that fits nice in the shoulders (not shown in the pic, that one is getting some work on the sleeves). The one that I'm talking about (not the one in the pic) is a black Zegna. I have two more Zegna's that are the same cut that the black Zegna but suprinsingly it is 3/8 larger that the other two Zegna's (Orange Line). So what he claims is that he can let the back out from the center (white large line) 3/8 of an inch from both sides (white little lines) in order to get the fit of the suit that fit well. He also thinks that this one (pictured above) needs less but still need the alteration. Thanks a lot! Cheers!
